We are using MSChart on an ASP.net 3.5 web application and noticing significant slowness from enabling tooltips. the performance of drawing a chart is increased by 1,000-2,000ms.The chart output is PNG, and contains in total 108 data points.
View 1 RepliesI have a pretty big web site (asp.net web) and I have used JavaScript intensively (jquery,custom javascipt, etc) and also The theme and CSS. Right now I have a huge amount of js and css files in my system and I am thinking about minifying and smashing the js and css to improve the performance. So, please advice me the suitable tools and technologies to be used and please suggest me the best practices to be applied in these scenario.
View 4 RepliesIn my webpage, the page uses lots of images and css. The time taken to load the initial home page is huge.What are the ways,which can be done in IIS 6.0 to improve the performance?I checked few results in google, which talked about File expiration policy and enabling http compression in IIS 6.0. In the Enable content expiration, what value should be ideally used?In the Custom Http header, what should be added to improve the performance.
View 4 RepliesI am working on a small project that requires gridview paging for upto 100k records. what are the ways i can improve the performance. I tried to page using sql server with Temp table but it still is a bit on the slower side.
View 3 RepliesI have developed a gridview which has 7,000 records with some filtering. However, theuser is compaining that it is too slow. It seems to me that if the records were stored in memory it would be much faster. This is caching, I think. Is that the case? Can you updaterecords this way? Can you cache with an Access database or do you have to use SQL Server? Can you think of any other ways to improve

View 1 RepliesI'm doing a timesheet program. In this timesheet program, I have a default button. If a person doing a same task everyday, they can just fill out the task description & click on default button, it will add that task for 5 days.my question is that my button click has to hit database 7 times. Is there anyway that I can improve this?

This is a continuation on this question:The problem is simple. I need to call methods from a REST web service which controls several tables. One table is a snapshot table which contains records with huge XML files. Each XML file is basically a backup from another database. This backup XML is then sent to customers who use the data as read-only information in another product. Basically, the data in the XML are lists of companies, products, business rules and whatever more. And no, those customers work offline most of the time, so they cannot get the data live.Walking through the list of snapshots is tricky: XMLData.Snapshots.Skip(N).Take(1).First(); but it works very nice. It's the answer of the previous Q.But there are three other lists of data that I need to walk through. These are called Changes, Errors and Messages. They contain (1) changes to the data, (2) errors that occurred during modifying the data and (3) generic messages. All of these records are linked to a snapshot record. Thus a single snapshot can contain multiple changes, errors and messages.
I still cannot access the server code but since there's a REST service wrapped around an entity framework exposing most of the functionality, I can still use that service. (And that service is only accessible internally, on the Intranet. This is basically what I have to work with. And while the lists of changes, errors and messages are relatively small, the snapshots are still huge.
The problem is that I now want to generate a client-side report of the changes, errors and messages, but without grouping them by snapshot! They need to be grouped by date. But each record also needs to show the title of the snapshot, which causes me some incredible headaches...When walking through e.g. the Changes with the regular foreach instruction I can load the Snapshot data by using XMLData.LoadProperty(Change, "Snapshots"); but since the snapshot record itself is generally about 300 MB, this just slows the whole thing down to a crawl. (There are tens of thousands of these records in total!) So I need a faster solution, without having to modify the server code.
Yeah, okay. Modifying the server would be the proper way but that's not possible. It's in production and this list isn't important enough to require an upgrade of the server. Basically, I'm not allowed to modify any server-code for now. (But they still want this list.)The application I'm working on is something that just needs to run once per week or per month. But with the current amount of records, I estimate it would take more than two days to finish. The data itself will be updated a few times every office day and snapshots are created every week or so on the server. Errors can always be generated when users start browsing the site which maintains the data but in general, there will be about 50 changes and 4 errors per week, plus a few messages when the server goes down and up again or when snapshots are generated.
I have developed a website in asp.net framework 2 . This website is being hosted in two different servers without any change in code. My issue is about the performance of these 2 sites. One website is taking much time for inserting datas to the DB (SQL server 2005). 2 websites are having different DB server.
I think the issue is for the DB server. How can we rectify the DB performance while insertion and Is there any other cause for this permance issue?
I am not sure if this is the right forum. I can not find a forum for LINQ.
I am working on an application using LINQ. Application performance is not up to par and my tests show that it is LINQ queries that are slow. I was wondering if anybody can recommend where I can find an article about optimizing LINQ performance maybe by compilation or other methods.
I am creating a service oriented application where trying to have everything using services....however there is something I am not sure of , I am having a page that calls the database at the page load...so what would be better and faster?? to call database in pageload , or to call wcf service from javascript during javascript load ??btw , I am using a repeater in the page , but I have created somekind of an engine to create the suitable html so...I'll be creating the repeaters html using the wcf and resend it back to the page If I am using a wcf service at the start.
View 1 RepliesIs there any working example of asp.net mvc with line chart of mschart?
View 5 RepliesI have a web application with several MSChart and I need print all these chart but I dont know how. In some examples in the internet people using EditCopy() but it dont working for me because I cant found that method.
View 17 RepliesI would like to customize the labels on the datapoints below so they would render as (using first datapoint on the chart as an example) :
4:10 - 4:40
yellow class
Got the MSChart working fine in a standard view, but I'm trying to put them on partial views that I'm then loading using jQuery tabs.
Problem is if you try to put the Chart on a partial, it moans about System.Web.UI.DataVisualization, saying it can't find it, no problem on a standard view though.
Can you use the new Microsoft Chart Control for .NET Framework inside a usercontrol? Bacause when i take a working chart from my page and then copy it to a usercontrol the picture is blank very weird.
View 1 RepliesI want to do a Jquery POST and get a chart using renderControl attribute of CHart which will return HTML attributes back to browser. The CHart is created dynamically based on parameters passed from post and from model. I have successfully done this on WEbforms,
However the same with MVC give a empty image. The handler doesn't perform the same in MVC2 3.5. I went near to 50 sites now.
I can't use other solution like base64encoding as IE6, 7 don't support it.
What I'm trying to do? I have few data parameteres to be sent (POST) to server and in response get the Chart image as tag along with other attributes and data appended in HTML form and sent to browser, all this to be done using JQUERY. No postbacks to be used.
I have badly searched on google, bing nothing turns out to be valuable.
I have installed the asp.net MSChart control for VS2008 and set up a chart on my webform. I am using DataBindTable in code to bind data from a LINQ query. The data for the x axis looks something like this:
Date/Time
15/03/2010 08:00:00
15/03/2010 14:00:00
15/03/2010 20:00:00
16/03/2010 08:00:00
16/03/2010 14:00:00
etc
When the chart displays the X axis only displays multiple dates, and not times, no matter what properties I try to change.
I need the capability to display a chart, click on a region and display the details in a jqgrid on the same page. I tried using a pie Chart and I can't seem to capture or create a click event for the chart. The data points contain a .url property which I can redirect to a different page but I need to display details on the same page like a master-detail page.
View 3 RepliesHow can I display a TimeSeries?Is it possible to use the MSChart Control (Asp.net Charting Control)?
View 3 RepliesI have an mschart control which is databound in code-behind. The Y axis values can vary from vary small to very broad. So the range is set to auto. This works fine except when the values in range of 0 and <1.
In this range the axis only has a zero, it does not have a "1" at top. Is it possible to set to dynamically set the maximum? So if the maximum value is less than one, still show a one.
i.e. get maximum value and set the Y axis maximum = maximum value +1
I tried to place 4 mschart controls on the same page but it is giving me major grief. Each chart appears properly when I place one per page, but as soon as I place multiple the first two are displaying incorrect data and the last two do no display anything at all.
I made sure that I am not using the same session variable eventhough that seems to be the most like culprit.
using Mschart on my MVC project,when i use the first index page of project to render for the partial view name index2 the code is
<% Html.RenderPartial("Index2"); %>
But when i run it the error is occur which the message is
CS0029: Cannot implicitly convert type 'ASP.views_home_index2_ascx' to 'System.Web.UI.Page'
-it said that the problem line of code is
: // Render chart control
Line 52: Chart2.Page = this;
[code]...
But when i put all of code in Index2.ascx to the index.aspx and not to render the partial view it work fine
Code of Index2.ascx is
<%
System.Web.UI.DataVisualization.Charting.Chart Chart2 = new System.Web.UI.DataVisualization.Charting.Chart();
Chart2.Width = 412;
Chart2.Height = 296;
[code]...
I'm using the MSChart Control in a Web Project. I saw that there are 3 different storage mode settings: file/memory/session. I couldn't find any information about the pros/contras or the impact of the settings.
View 2 RepliesI am using the .net 3.5 chart controls and I am binding a chart to a datatable datasource. How do you keep the charts displayed after a postback has ocured. I bind my chart control. The on the page i make a change to a dropdownlist that issues a postback to the server. When the page reloads the charts have no data. How can you make the chart object persist it's data during postback?
